    Are wooden cutting boards kosher? They seem to be finished with oil. Probably pig oil.

    I asked one national hashgacha. They said it is cold, so I said I want to cut hot peppers. So they it’s fine because it’s probably kosher and is eino ben yomo. But isn’t a davar charim mechalia l’shvach? And why assume it is probably kosher? I assume it is pig fat.

    I asked another national hashgacha. They said you can’t use it. So I asked if their supervised establishments have special vendors I could buy from, because I’m betting they all use them.

    Are wood blocks kosher?

    I’m not familiar with the parameters of that.

    But I assume you’re trying to say there’s some sort of assumption that the oil is kosher, since I don’t imagine that it means you can eat random oil you find. So, why are you assuming that?

    I don’t know why one would assume that the oil used on wooden cutting boards comes from pigs.

    Oils most commonly recommended for wood items that come in contact with food – like cutting boards – are:

    1 – White mineral oil, a petroleum derivative

    2 – Pure beeswax – Rav Dovid Heber states that it’s kosher

    3 – Coconut oil

    4 – Carnauba, from palm tree

    5 – Tung oil (no, not tongue), from Tung tree, bad for

    those allergic to nuts

    6 – Linseed oil (raw, not boiled), from flax plant

    7 – walnut oil

    8 – Shellac or lacquer, which is a secretion of the lac insect and Rav Dovid Heber quotes Rav Moshe as holding that it is no different than honey in this respect and is a kosher product.

    Interesting topic, thanks for bringing to our attention 🙂

    I did a quick Google search (amazing how much you can learn), and see that the standard (therefore Rov) finish for wooden cutting boards is mineral oil, which would not be a problem. Some use a combination of linseed (flax) and mineral, which is also not an issue. Of course, if you know that your cutting board was finished with lard……

    GAW: So you think there’s a rov that paskens the cutting board in front of you was finished with mineral oil?

    Can you just please walk us through the kuf yud aleph analysis, for those of us a bit rusty on the rules.

    I think you would first need to establish that animal fats are ever used in order to even need a rov.

    I think a better way of saying what you’re saying is that there’s a very strong rov?

    If I find a piece of meat in a sack, there’s a safeik what it is. If you found out that only kosher meat is stored in sacks and treif meat is always stored in bags, that might create a rov.

    If you are worried, sand it down and re oil it with mineral oil.

    No, I think the way I said it is fine. I don’t think your case of the meat sack is a rov either.

    Are lobster shells food?

    This isn’t a case where you found a rock and you’re wondering whether its really a potato. You found oil-)ou can’t just assume its kosher until you find out otherwise. I don’t agree.

    So like the oil in cutting boards, it’s nosein ta’am lifgam.

    As noted above, I’m cutting hot peppers, so hot they would burn a hole in a cow’s stomach.

    Wooden cutting boards are worse avodah zarah than Zionism is. It’s showing that you care about your knives. Knives should not be worshipped.

    1) I can’t imagine they wouldn’t add pagum chemicals to prevent the pigs’ oil from stinking worse than a cow’s stomach.

    2) Even l’shitascha hat’uyah, apushatayid’s eitzah would work.

    3) I hope your stomach is stronger than a cow’s.

    It’s a cutting board, not a bridal veil.

    What would I reseason it with? The block oil doesn’t have a hechsher, and there’s no eid echod.

    It isn’t for me. http://www.theyeshivaworld.com/coffeeroom/topic/hashgacha-pratis-2

    Good question. Will have to ask the Home Depot posek what the sand paper is made from.

    Or the block oil. You are not actually putting it into your food, and it’s essentially a kosher item.

    How do you know it’s kosher? If it says rice oil then it must be rice oil? Is that how eid echod neeman b’isurin works?

    Pretty sure yitay would agree with me on this one. This isn’t food where yitay would say you can trust the label that they put inside what they wrote because there is regulation. Block oil is not regulated.

    If you are confident that they are assur, then don’t use one. If you are not sure, ask your posek.

    1. Hagalah works on wood

    2. A davar charif needs duchka d’sakina (or heat) to extract taam (and the pressure from the board doesn’t count, there is a tshuva from R’ Yitzchak Elchonon on this…)

    A. I don’t have a pot big enough to dip it.

    B. I don’t want to ruin the finish.

    C. Pot is assur.

    I’m pretty sure we’re noheig that cutting boards are an issue. Google around.

    I mistakenly quoted R’ Yitzchak Elchanan, it is actually from R’ Chaim Berlin (funny two people to confuse!), ???? ???? ???? ?”? excerpted below:

    As far as the minhag, I am not sure who the ???? ??? is quoting as being a maikel (and then rejecting) but the ???? ???? is comfortable to state his heter as an absolute pashtus…

    As far as Hagalah goes, irui should work. I would be quite surprised if the board was immersed in a vat of hot oil…

    No. Plastic is made from non-organic substances.

    Nu, google around and you’ll find the machmirim also.

    And I have no idea how they apply the oil. Maybe the machine runs them through a hot bath–how should I know?
